Audio sub-systems on Linux
by Ian McDonald 20 Jul '06

20 Jul '06

I notice that Craig discusses these a bit on his latest blog at: http://craig.dubculture.co.nz/blog/2006/07/20/audio-on-ubuntu/ Craig - can you (or anyone else?) explain to me how Jack fits into all of this? Jack is mentioned at: http://jackit.sourceforge.net/docs/faq.php http://jackaudio.org/ I've seen quite a bit of mention of Jack around the place (as well as GStreamer) and haven't noticed PulseAudio much at all. It seems clear that OSS is going away and what Craig says about ESD makes sense as well... Now Alsa is at the kernel level for devices and doesn't seem to face any real competition. How do the other bits fit togther though?

SCO OpenServer 5
by zcat 19 Jul '06

19 Jul '06

If anyone has the install disk(s) for SCO OpenServer, I would be very interested in getting hold of them. I'm trying to migrate someone from a legacy system to Linux and it would be very handy (almost essential!) to set up a mirror of their current server to work with.

router disconnecting
by Haldor Riddering 19 Jul '06

19 Jul '06

Hi people, okay I had a big crash and lost loads of data in windows plus system got trashed so decided to give ubuntu dapper a go on my laptop. no worries after much hacking away got everything working how I want it. now however there is a problem. I have a dlink dsl-302g modem. now whenever I run the laptop after a few minutes the router disconnects then reconnects and this happens again and again whenever the laptop is on. it doesn't happen with my windows machines and if I turn the laptop off the connection is constant for 24+ hours. I emailed the slingshot help desk and they say it's a line fault and it's going to cost $88 to have it looked at. but it only happens when the laptop is on the network. any ideas about whats happening here? I'm very happy with ubuntu, just frustrated with the disconnects. I have tried a second dsl-302g so it's not the router and the internal network works flawlessly just the internet connection is screwy. Cheers Haldor

Local Linux training
by Eric Light 19 Jul '06

19 Jul '06

Hi all, My name is Eric, I've been following this list for about two years now but haven't had occasion to actually make a post until now... I've been looking for a training institute which offers a course towards the CompTIA Linux+ certificate. I was offered a scholarship in Auckland for such a course, but I'm really looking for somewhere in Hamilton. My experience with Linux is minimal - I've installed a few older versions of Mandrake in the past, and more recently got most of a server going with Ubuntu. But I still honestly don't really know what I'm doing, and most of the time I rely on programs which feature a GUI. I'd like to get away from that. I've called Hamilton Business School (http://www.hbsc.co.nz/index.asp?PageID=2145824273) who seem to be the only ones in Hamilton offering the course, but their Linux tutor has recently left the company and so they're not offering the course at the moment. Does anyone know of a Hamilton training provider where I could do something along the lines of a 20-week course via Student Loan? Thanks in advance, - Eric Light

Squid content admin tool
by Ian McDonald 18 Jul '06

18 Jul '06

Folks, I'm just being lazy here and not looking it up myself. Can anyone tell me a good squid admin tool that allows to alter whitelisted and blacklisted URLs by user/group? I can just alter the config files I know but it'd be nice to have a web front end to it. Would be cool if it has reporting too but that's not a major.

Xen news
by Ian McDonald 17 Jul '06

17 Jul '06

>From http://www.osnews.com/story.php?news_id=15210 Lots of news on Xen. Firstly, "This is a document about how to set up XEN and iSCSI on 3 Debian Stable machines so that you can have a virtual host that can be migrated live between 2 of the machines. The third machine will be the common disk for the virtual machine that is seen via the 2 machines running XEN." Secondly, "IBM and Novell are throwing their considerable weight behind Xen, but some experts are suggesting that these companies may be pushing this nascent technology too far too fast." Lastly, "You can now run OpenSolaris domains under Xen as dom0 with OpenSolaris domUs too." To get to the stories mentioned here go to the osnews URL. -- Ian McDonald Web: http://wand.net.nz/~iam4 Blog: http://imcdnzl.blogspot.com WAND Network Research Group Department of Computer Science University of Waikato New Zealand

The Waikato Linux Users Group have a meeting in one week from today: ---------------------------------------------------------------------- Our July guest is Roger de Salis, a director of http://www.wlug.org.nz/FxNetworks. FX Networks are a http://www.wlug.org.nz/Wellington company with significant http://www.wlug.org.nz/Unix and http://www.wlug.org.nz/Cisco Networking experience. The principals of FX have over 50 years experience in the IT and Telecommunications industry, the bulk of which is about continuously available on-line systems for public use. They specialise in bringing interesting technical ideas to market. FX believe you should be able to get connectivity far greater than what is currently available in New Zealand, and have made great investment in a fibre network around New Zealand. They're also pioneers in the use of http://www.wlug.org.nz/VoIP. If you're interested in the InterNet or telephone calls, this is a meeting not to be missed!

Re: [wlug] hosts file
by David Bowen 16 Jul '06

David wrote Hi After playing with my networking settings in Breezy, I seem to have lost some data from my /etc/hosts file. Partly it requires editing to add to add "ubuntuDavid" to it. However without it I can't log in as root to edit it. Can't find password! I can't edit it with Knoppix, I don't have permission. Is there any way to edit it or is it a reinstall job. As it is I can't connect to the net or anything requiring root privilege. Thanks David Bowen > Shane wrote: > > Hi Dave, > The file probably needs permissions changed for it to be edited under knoppix > chmod a+w /mount/drive/etc/hosts > > If this still doesnt work, its time to boot to single user mode <g> > This should give you some direction > from > http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-res… > > Select Ubuntu with the version of the kernel that you wish to boot and type e > for edit.

Thinking about it My command was probably trying to execute the file rather than open it and root did not have permission to execute it. I will look at the book I have at work to look into that next week. Then I can change the permission back again! I have to admit I tend to use command line only when necessary, but I am starting to get the hang of it Thanks all for the help. * > > >> >> > Here's a possibility: > > root doesn't have a password set at all under ubuntu.
